Excavation work is well underway at the site of a planned 59-story, 458-unit mixed-use tower under development at 138 Willoughby Street, located on the corner of Flatbush Avenue Extension in Downtown Brooklyn. A photo reveals multiple excavators active on site, as well as footings for the foundation. The latest building permits have the project measuring 686,830 square feet and rising 696 feet to its parapet.

Retail space, totaling roughly 68,000 square feet, will be located across the cellar through third floors. The condominium residential units will begin on the seventh floor and end on the 58th floor. Extell Development Company is the developer and Kohn Pedersen Fox is the design architect. SLCE Architects is the executive architect and completion is expected in early 2021.
